For me showering means standing in a windowless room staring at a blank wall for 20 minutes (I get lost in my thoughts). Also there are several steps and I have to think about each of them.
This means that I only end up showering when my fear of coming across as dirty becomes bigger than the dread of being bored.
What do you do?
Nothing wrong with a weekly shower in some conditions.
A good podcast or TV show might help.
